Mandibular central-incisor means were taken as pre-registered: the Romanian pooled pair, the unweighted mean of the JECS male and female means, the Indian common parenthetical age in months, and the unweighted mean of the Spanish left and right mandibular means. T is their unweighted mean. Order compares incisor and molar class means inside each cohort. The seventh month of life is ages 6 up to 7 months; T at or above 8 months refutes. https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: 9.5713 months, unweighted mean of study-level mandibular central-incisor estimates (n = 4, 4.085). Interpretation: 'In the seventh month' is read as the seventh month of life, ages 6 up to but not including 7 months, not as a rounded age of 7 months. The alternative window [6, 8] is computed and reported and does not decide the verdict. 'Front teeth' are the incisors. The claim's clause that warmer nurse's milk brings teeth sooner is outside this test. Aristotle is stating a norm for children, so disagreement among populations counts against a single age. https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ha07-21: refutes, confidence 0.8 https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ha07-21/result.json https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test https://w3id.org/delphi/ontology/admissibleDatasets Open pediatric cohorts that report a mean or median eruption age, with a sample size, for primary incisors and for at least one molar class.

Eruption order is the rank of class means inside each cohort. https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test https://w3id.org/delphi/ontology/passCriterion Pre-registered. The seventh month of life is chronological age in the half-open interval [6, 7) months (the child has finished six months and has not yet finished seven). For each of the four cohorts, the study estimate is the pooled mean eruption age of the mandibular central incisor; if only sex-specific means exist, their unweighted mean; if left and right are given separately, their unweighted mean; if a parenthetical age in months accompanies a value in days, use the months figure. T is the unweighted mean of the four study estimates. Timing passes if T is in [6, 7). Order passes if, in every cohort, the tooth class with the smallest central estimate is an incisor and the smallest molar estimate is later than the smallest incisor estimate. Supports only if timing passes and order passes. The milk-temperature clause and the 'sometimes upper, sometimes lower' clause are not scored: these tables do not record milk temperature, and a study mean cannot show that some individual children erupt an upper tooth first. https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/aristotle-ha07-21 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/aristotle-ha07-21--claim-test https://w3id.org/delphi/resource/evidence/aristotle-ha07-21--claim-test--dataset-1 http://purl.org/dc/terms/description mean eruption age by primary tooth https://w3id.org/delphi/resource/evidence/aristotle-ha07-21--claim-test--dataset-1 http://purl.org/dc/terms/license Licensee MDPI, Basel, Switzerland.
